The collecting electrode 13 is an array electrode, a metal electrode or a flexible electrode, and the electrodes can be attached to corresponding areas on the surface of the handle through processes of coating, adhering and the like. In order to meet the requirements of different people, the surface of the handle is provided with a circle of collecting electrodes, so that no matter which part of the handle is held by an unlocking person, the corresponding collecting electrodes collect the myoelectric signals of the hands of the unlocking person.
Fig. 3 shows a high-density array type collecting electrode, and the collecting electrode 13 can collect electromyographic signals of different muscle positions of the palm through multiple channels.
The handle can adopt shapes such as a cylinder shape suitable for being gripped by a palm and an ergonomic structure, and the purpose of the handle is not only to comfortably grip the lock handle, but also to enable palm muscles to tightly fit with the acquisition electrodes on the gripping surface of the handle in the gripping process.
As shown in fig. 4, the lock further comprises a storage mechanism 161 for storing a set of reference characteristic information. The processing mechanism 14 is preferably implemented by a hardware circuit, and its functions include, but are not limited to, electromyographic signal filtering, feature information extraction, feature matching, and the like, wherein the feature information includes, but is not limited to, average absolute amplitude, waveform length, and the number of zero-crossing points. The processing means 14 obtains the feature information corresponding to the electromyographic signal, compares the feature information with the reference feature information in the reference feature information set stored in the storage means 161, and outputs an unlocking signal or a locking signal when the comparison result matches.
The number of the reference characteristic information sets can be only one, and if the lockset only needs to be unlocked by a secret key, the characteristic information corresponding to the electromyographic signals in the unlocking process can be compared with the reference characteristic information in the reference characteristic information sets; if the lockset needs to be unlocked by the secret key and locked by the secret key, the unlocking and locking adopt the same reference characteristic information, namely, the characteristic information corresponding to the myoelectric signal in the unlocking process and the characteristic information corresponding to the myoelectric signal in the locking process are compared with the reference information in the reference characteristic information set, namely, the unlocking and locking can be realized by the same hand action of an unlocking person; of course, there may be two reference characteristic information sets, one is an unlocking reference characteristic information set corresponding to an unlocking operation, and the other is a locking characteristic information set corresponding to a locking operation, and at this time, the door opener needs to perform the unlocking operation and the locking operation by using different preset hand motions. The method specifically comprises the following steps: if the current lockset is in an open state, the processing mechanism can judge whether the characteristic information corresponding to the current electromyographic signal exists in a locking reference characteristic information set corresponding to locking operation, and if the current lockset is in a closed state, the processing mechanism can judge whether the characteristic information corresponding to the current electromyographic signal exists in an unlocking reference characteristic information set corresponding to unlocking operation.
The preset hand motion may be a palm grasping motion, a motion of a single finger, such as bending of an index finger, or a simultaneous motion of a plurality of fingers, such as bending of an index finger and a middle finger, and may be one motion or a plurality of motions. If the hand movement sequence is the same as the preset hand movement sequence, the characteristic information at least comprises characteristic information corresponding to two preset hand movements and time sequence information corresponding to different preset hand movement appearance sequences. At this time, the processing unit 14 is configured to determine whether all the feature information corresponding to the extracted electromyographic signals exist in the corresponding reference feature information set, and whether the time sequence information of the feature information corresponding to each preset hand motion meets a preset time sequence, and if all the feature information corresponds to the preset time sequence, output an unlocking signal or a locking signal.
Preferably, the lockset can be set to unlock based on characteristic information corresponding to myoelectric signals of a plurality of unlocking persons.

For the composite lock based on various physiological signals, the occurrence time sequence of various physiological signals can be not considered, and the occurrence time sequence of various physiological signals can also be considered. Taking a lockset combining an electromyographic signal and a fingerprint as an example, if the occurrence time sequence of various physiological signals is not considered, as long as the characteristic information corresponding to the acquired electromyographic signal and the characteristic information corresponding to the fingerprint signal both exist in the corresponding reference characteristic information set, and the characteristic information in the corresponding reference characteristic information set belongs to the same person, the processing mechanism 14 outputs an unlocking signal or a locking signal; if the occurrence time sequence of various physiological signals is considered, the electromyographic signals and the fingerprint signals which need to be collected appear in a preset time sequence, the characteristic information corresponding to the electromyographic signals and the fingerprint signals respectively exists in the corresponding reference characteristic information sets, and when the characteristic information in the reference characteristic information sets corresponding to the electromyographic signals and the fingerprint signals belongs to the same person, the processing mechanism outputs unlocking signals or locking signals.

It will be appreciated that the reference characteristic information is first established by the door opener when the lock is first used. When the reference characteristic information is established, a reference characteristic information establishing request needs to be input into the lockset. After the request is input, the requester holds the handle and executes one or more actions, the control mechanism acquires the electromyographic signals of the current door opener through the surface electrodes of the handle, extracts the characteristic information corresponding to the acquired electromyographic signals through the processing mechanism, and establishes the reference characteristic information corresponding to the current door opener according to the extracted characteristic information, so that the lock can be opened or closed when the door opener holds the handle and executes the action when the reference characteristic information is established. Of course, when the door opener changes the password, the door opener also needs to re-enter new reference characteristic information.

The handle can hide the finger action when being held, so the preset hand action is one-layer protection for the lock, and even if the same finger action is carried out, the electromyographic signals reflected by different people are different, the one-layer protection is also one-layer protection for the lock, and compared with the fingers, a palm is not easy to be injured, so that the myoelectricity signals collected by the palm are used for triggering the unlocking action and/or the locking action, and the safety is high.
